Sadly the days of conviction politicians such as Benn, Skinner, Thatcher , Foot etc are long behind us, now you have a professional class of politician who basically has no real outside experience of life but that of that in the gravy train, from university politics straight into a job working for a politician or party and then through promotion up to an MP.
If your mates cant get you into a safe seat as an MP, don’t worry, there’s always opportunities in Brussels, the local council or Quango.
I blame the electorate, someone has to vote for them, its not a complete charade!
